Abstract. We evaluated the chemical sequestration of carbon dioxide into the phosphogypsum from the Lowveld region of South Africa. The phosphogypsum was converted to saleable ammonium sulphate and precipitated calcium carbonate in a modified Merseburg process.

The product of the process, anhydrous sodium carbonate, is obtained as a fine white powder known as light sodium carbonate. (6) Formation of calcium hydroxide The last two stages, (6) and (7), are concerned with the regeneration of ammonia from ammonium chloride (made in step 3).
